> Kava API is available on [Web3 API platform](https://crypto-chief.com/rpc/kava/).

*Kava* is a Layer 1 blockchain with a co-chain architecture: an EVM-compatible execution layer runs alongside a Cosmos SDK application layer, enabling interoperability with both EVM dApps and the Cosmos IBC ecosystem from a single network. KAVA is the native token used for gas, staking, and governance on both chains.

The EVM co-chain exposes a standard Ethereum [JSON-RPC](https://www.jsonrpc.org/specification) interface, making existing Solidity contracts and Web3 tooling immediately compatible.

### EVM JSON-RPC methods

* [`web3_clientVersion`](#web3_clientversion) — returns the current client version.
* [`web3_sha3`](#web3_sha3) — returns Keccak-256 (not the standardized SHA3-256) of the given data.
* [`net_version`](#net_version) — returns the current network ID.
* [`net_listening`](#net_listening) — returns true if client is actively listening for network connections.
* [`eth_protocolVersion`](#eth_protocolversion) — returns the current protocol version.
* [`eth_syncing`](#eth_syncing) — returns data on the sync status or false.
* [`eth_gasPrice`](#eth_gasprice) — returns the current price per gas in wei.
* [`eth_accounts`](#eth_accounts) — returns a list of addresses owned by client.

  1. `<string>` (data, 20 bytes): an address to check for balance.
  2. `<string>` (quantity|tag): either the hex value of a *block number* or one of the following *block tags*:
     * `earliest`: the lowest numbered block available on the client.
     * `finalized`: the most recent crypto-economically secure block; cannot be re-orged outside of manual intervention driven by community coordination.
     * `safe`: the most recent block that is safe from re-orgs under honest majority and certain synchronicity assumptions.
     * `latest`: the most recent block in the canonical chain observed by the client; this block can be re-orged out of the canonical chain even under healthy/normal conditions.
     * `pending`: a sample next block built by the client on top of the `latest` and containing the set of transactions usually taken from local mempool. In other words, it is the block that has not been mined yet.

#### Returns

* `<string>` (quantity): the current balance in wei.

### `eth_getStorageAt`

> Returns the 32-byte value stored at a given storage slot of a contract.

#### Parameters

* `id` (integer; required): a request ID (example: 1).
* `jsonrpc` (string; required): a JSON RPC spec used (example: 2.0).
* `method` (string; required): a method used for the request.
* `params` (array; required):
  1. `<string>` (data, 20 bytes): an address of the storage (hex encoded).
  2. `<string>` (quantity): a slot position in the storage (hex encoded unsigned integer).
  3. `<string>` (quantity|tag): either the hex value of a *block number* or one of the following *block tags*:
     * `earliest`: the lowest numbered block available on the client.
     * `finalized`: the most recent crypto-economically secure block; cannot be re-orged outside of manual intervention driven by community coordination.
     * `safe`: the most recent block that is safe from re-orgs under honest majority and certain synchronicity assumptions.
     * `latest`: the most recent block in the canonical chain observed by the client; this block can be re-orged out of the canonical chain even under healthy/normal conditions.
     * `pending`: a sample next block built by the client on top of the `latest` and containing the set of transactions usually taken from local mempool. In other words, it is the block that has not been mined yet.

#### Returns

* `<string>` (data): the value at this storage position.

### `eth_call`

> Executes a read-only call against the EVM state without broadcasting a transaction.

#### Parameters

* `id` (integer; required): a request ID (example: 1).
* `jsonrpc` (string; required): a JSON RPC spec used (example: 2.0).
* `method` (string; required): a method used for the request.
* `params` (array; required):
  1. `<object>` (hex encoded): the transaction object:
     * `from` (string; data, 20 bytes; optional): the address the transaction is sent from.
     * `to` (string; data, 20 bytes): the address the transaction is directed to.
     * `gas` (string; quantity; optional): the gas provided for the transaction execution. `eth_call` consumes zero gas, but this parameter may be needed by some executions.
     * `gasPrice` (string; quantity; optional): the gas price willing to be paid by the sender in wei.
     * `value` (string; quantity; optional): the value sent with this transaction, in wei.
     * `data` (string; data; optional): the hash of the method signature and encoded parameters.
  2. `<string>` (quantity|tag): either the hex value of a *block number* or one of the following *block tags*:
     * `earliest`: the lowest numbered block available on the client.
     * `finalized`: the most recent crypto-economically secure block; cannot be re-orged outside of manual intervention driven by community coordination.
     * `safe`: the most recent block that is safe from re-orgs under honest majority and certain synchronicity assumptions.
     * `latest`: the most recent block in the canonical chain observed by the client; this block can be re-orged out of the canonical chain even under healthy/normal conditions.
     * `pending`: a sample next block built by the client on top of the `latest` and containing the set of transactions usually taken from local mempool. In other words, it is the block that has not been mined yet.

#### Returns

* `<string>` (hex encoded bytes): the return value of executed contract.

### `eth_estimateGas`

> Simulates a transaction and returns the estimated gas units it would consume.

The transaction will not be added to the blockchain. Note that the estimate may be significantly more than the amount of gas actually used by the transaction, for a variety of reasons including EVM mechanics and node performance.

#### Parameters

* `id` (integer; required): a request ID (example: 1).
* `jsonrpc` (string; required): a JSON RPC spec used (example: 2.0).
* `method` (string; required): a method used for the request.
* `params` (array; required):
  1. `<object>` (hex encoded): the transaction object:
     * `from` (string; data, 20 bytes; optional): the address the transaction is sent from.
     * `to` (string; data, 20 bytes; optional): the address the transaction is directed to.
     * `gas` (string; quantity; optional): the gas provided for the transaction execution. `eth_call` consumes zero gas, but this parameter may be needed by some executions.
     * `gasPrice` (string; quantity; optional): the gas price willing to be paid by the sender in wei.
     * `value` (string; quantity; optional): the value sent with this transaction, in wei.
     * `data` (string; data; optional): the hash of the method signature and encoded parameters.
  2. `<string>` (quantity|tag; optional): either a HEX value of a *block number* or one of the following *block tags*:
     * `earliest`: the lowest numbered block available on the client.
     * `finalized`: the most recent crypto-economically secure block; cannot be re-orged outside of manual intervention driven by community coordination.
     * `safe`: the most recent block that is safe from re-orgs under honest majority and certain synchronicity assumptions.
     * `latest`: the most recent block in the canonical chain observed by the client; this block can be re-orged out of the canonical chain even under healthy/normal conditions.
     * `pending`: a sample next block built by the client on top of the `latest` and containing the set of transactions usually taken from local mempool. In other words, it is the block that has not been mined yet.

#### Returns

* `<string>` (quantity): the amount of gas used.

### `eth_getTransactionByBlockNumberAndIndex`

> Returns the transaction at the specified index within the block at the given height.

#### Parameters

* `id` (integer; required): a request ID (example: 1).
* `jsonrpc` (string; required): a JSON RPC spec used (example: 2.0).
* `method` (string; required): a method used for the request.
* `params` (array; required):
  1. `<string>` (quantity|tag): either the hex value of a *block number* or one of the following *block tags*:
     * `earliest`: the lowest numbered block available on the client.
     * `finalized`: the most recent crypto-economically secure block; cannot be re-orged outside of manual intervention driven by community coordination.
     * `safe`: the most recent block that is safe from re-orgs under honest majority and certain synchronicity assumptions.
     * `latest`: the most recent block in the canonical chain observed by the client; this block can be re-orged out of the canonical chain even under healthy/normal conditions.
     * `pending`: a sample next block built by the client on top of the `latest` and containing the set of transactions usually taken from local mempool. In other words, it is the block that has not been mined yet.
  2. `<string>` (quantity): the transaction index position.

#### Returns

* `blockHash` (string; data, 32 bytes): a hash of the block containing the transaction; null when it's pending.

     * `toBlock` (string; quantity|tag; optional; default: "latest"): either the *block number* or one of the following *block tags*:
       * `latest`: for the last mined block.
       * `earliest`: for the lowest numbered block available on the client.
       * `pending`: for not yet mined transactions.
     * `address` (array of strings; data, 20 bytes; optional): a contract address or a list of addresses from which logs should originate.
     * `topics` (array of strings; data; optional): an array of 32 bytes data topics. Topics are order-dependent. Each topic can also be an array of data with "or" options.
     * `blockhash` (string; data, 32 bytes; optional; **future**): with the addition of EIP-234, `blockHash` will be a new filter option which restricts the logs returned to the single block with the 32-byte hash blockHash. Using blockHash is equivalent to `fromBlock = toBlock = the block` number with hash blockHash. If `blockHash` is present in the filter criteria, then neither `fromBlock` nor `toBlock` are allowed.

#### Returns

* `removed` (string; tag): `true` when the log was removed, due to a chain reorganization; `false` if it's a valid log.
* `logIndex` (string; quantity): the log index position in the block; null when it's a pending log.
* `transactionIndex` (string; quantity): the transactions index position log was created from; null when it's a pending log.
* `transactionHash` (string; data, 32 bytes): a hash of the transactions this log was created from; null when it's a pending log.
* `blockHash` (string; data, 32 bytes): a hash of the block containing the log; null when it's pending; null when it's a pending log.
* `blockNumber` (string; quantity): the number of the block containing the log; null when it's pending; null when it's a pending log.
* `address` (string; data, 20 bytes): an address from which this log originated.
* `data` (string; data): contains one or more 32 bytes non-indexed arguments of the log.
* `topics` (array of strings; data): an array of 0 to 4 32 bytes data of indexed log arguments. (In solidity: The first topic is the hash of the signature of the event (e.g. Deposit(address,bytes32,uint256)), except you declared the event with the anonymous specifier.)

### Information

#### `blockchain`

> Retrieves block headers for `minHeight <= height <= maxHeight`.

At most 20 items will return for the `minHeight` or `maxHeight` parameters specified. If `maxHeight` does not yet exist, the blocks up to the current height will return. If `minHeight` does not exist (pruning), the earliest existing height will be used.

**Parameters**

* `minHeight` (integer): the minimum block height to return.
* `maxHeight` (integer): the maximum block height to return.

**Returns**

Block headers, in descending order (highest first).

### Transactions

#### `broadcast_tx_sync`

> Returns with the response from `CheckTx`. Does not wait for `DeliverTx` result.

If you want to be sure that the transaction is included in a block, you can subscribe for the result using JSON-RPC via a websocket. See <https://docs.cometbft.com/v0.34/core/subscription.html> If you haven't received anything after a couple of blocks, resend it. If the same happens again, send it to some other node. A few reasons why it could happen:

1. A malicious node drops or pretends it has committed your tx.
2. A malicious proposer (not necessary the one you're communicating with) drops transactions, which might become valid in the future ([tendermint/tendermint#3322](https://github.com/tendermint/tendermint/issues/3322)).

Please refer to [Tendermint docs](https://docs.tendermint.com/v0.34/tendermint-core/using-tendermint.html#formatting) for formatting/encoding rules.

#### Parameters

* `tx` (string; required): the signed transaction, encoded as Base64.

**Request example**

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": {
    "code": 0,
    "data": "",
    "log": "transaction successfully broadcasted",
    "hash": "0xABC123..." // The transaction hash
  }
}
```

***

#### `broadcast_tx_async`

> Returns right away, with no response. Does not wait for `CheckTx` nor `DeliverTx` results.

If you want to be sure that the transaction is included in a block, you can subscribe for the result using JSON-RPC via a websocket. See <https://docs.cometbft.com/v0.34/core/subscription.html> If you haven't received anything after a couple of blocks, resend it. If the same happens again, send it to some other node. A few reasons why it could happen:

1. A malicious node drops or pretends it has committed your tx.
2. A malicious proposer (not necessary the one you're communicating with) drops transactions, which might become valid in the future ([tendermint/tendermint#3322](https://github.com/tendermint/tendermint/issues/3322)).
3. A node is offline.

Please refer to [CometBFT docs](https://docs.cometbft.com/v0.34/core/using-cometbft.html#formatting) for formatting/encoding rules.

**Parameters**

* `tx` (string; required): the Base64-encoded signed transaction.

**Request example**

{% tabs %}

}
```

***

#### `broadcast_tx_commit`

> Returns with the responses from `CheckTx` and `DeliverTx`.

Use only for testing and development. In production, use \`BroadcastTxSync\` or \`BroadcastTxAsync\`. You can subscribe for the transaction result using JSON-RPC via a websocket (see \[CometBFT docs]\(<https://docs.cometbft.com/v0.34/core/subscription.html>)). CONTRACT: only returns error if \`mempool.CheckTx()\` errs or if we timeout waiting for tx to commit. If \`CheckTx\` or \`DeliverTx\` fails, no error will be returned, but the result will contain a non-OK ABCI code. Please refer to \[CometBFT docs]\(<https://docs.cometbft.com/v0.34/core/using-cometbft.html#formatting>) for formatting/encoding rules.

**Parameters**

* `tx` (string; required): the Base64-encoded signed transaction.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs-rpc.crypto-chief.com/chains/kava.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
